You refer to the prints. I have reviewed the prints for the fuel tanks and see no reference to this, I also looked on line at what wing prints I have there and don't see any reference. Was this included in the paper prints that were sent with the wing kit? If so, I apologize for having to ask the question, but I have not seen those prints in months.

I noticed that you are dimpling the skin and the tank back at the same time, together. Is this to insure a perfect fit between the two? I never thought of that and glad you posted the reference to your Picasa.

I see an additional line of holes that you used to rivet the tank to the wing. In that everything is now pre-punched, is that the way it is now done? I don't see any reference to marking and drilling these, in the plans, but I am known to over-look things.

Thank you very much for your reply and if you have time, please send a little clarification on these.

Dan,

Prints and BM for attaching tanks have not yet been published. For my tanks, all mounting holes were located/drilled after the tanks were completed. For tank parts that have already been joined and require dimpling, both parts must be dimpled at the same time. When asking questions about specific Picasa photos, it would be helpful to note the number of the photo. If I missed an answer, please ask again.

Tony

I want to add a note to what Rachel posted about these. They are so perfect that you do not need tape to protect the skin, in fact, the tape gets in the way. They and the match drill, turn this whole process from what could be a nightmare, into a pleasant dream. Messing up one of these tank skins, will cost you a bunch more than the very reasonable price of the Saddles. Even if you are experienced, (my RV friends were in awe, at least those who had to build their own tanks) you will definitely get more than your money worth from them.

No - not at all.

The saddles are wood fixtures to properly fixture the fuel tanks in while building. We have sets in stock and they are $45 plus shipping. We have a few sets in stock and will add them to the web store tomorrow. If you need them (if you are building your own tanks and don't want to cut them out yourself then you do) send support@flywithspa.com an email, or order online.

Wow, match drilled, Dan W. is taking all the fun out of building! (just kidding, glad I ended up later on the kit shipment list). What are the saddles you mentioned Dan, wood fixtures the tanks are built in?

BTW, you who are afraid of building the tanks, don't worry. The new ones are match drilled and if you get the saddles from SPA, I don't see how you can go wrong. Yes, everything is not intuitively obvious unless you are someone who has built tanks like this before, but it surely isn't rocket science. I will be posting pics of my build so anyone who is concerned can see how a first time metal airplane builder did it.

But, I sure would like to see some pictures of the final installation.

Thanks for your time, in advance.
